Ooni Premium Hardwood 5" Oak Logs come from sustainably sourced, 100% oak. Our hardwood kindling is free from chemicals, aromas or additives, for a pure fuel that infuses your dishes with all-natural flavors and burns for longer. Perfectly sized for the Ooni Karu range, keep 5 or 6 pieces of kindling burning at a time for consistent heat. Each 15-17.5 lbs box will last enough to cook dozens of pizzas. Our Oak Logs are kiln-dried and FSC certified. Please note that wood logs are a natural product in varying shapes and sizes. What you receive may differ from the images shown on this page, but they will fit and fuel your Ooni oven.
